TRANSOM CONTROLLER Refiled for abandoned application Serial No. 215,218,filed February 2, 1918. This applioation'filed May 2, 1929. Serial n359,9?1. Y

This invention relates to new and useful improvements in transomcontrollers, being a refiling of application filed Feb. 2, 1918, SerialNo. 215,218, abandoned March 7, 1924, 5 and theprincipal object of theinvention is to provide a device adapted for opening and closingordinary hinged transoms by the mere pulling of a chain. 7 I Anotherobject of the invention is to pro- 10 vide. a spring for holding thetransom in either open or closed position which spring holds thedevicein either of its positions and also acts to move the same when theconnecting links are in proper position for such 15 movement.

A still further object of the invention is to Figure 2 is a sectionalview on line 22 of Figure 1 showing the same on an enlarged scale andillustrating the transom closed,

Figure 3 is a view illustrating the transom opened, and i i Figure 4 isa diagrammatic view of the device showing the method of operation.

Referring to the drawings the numeral 1 designates an ordinary doorcasing having hingedly connected thereto the transom 2 which'ispreferably hinged at its lower edge to thelintel and is arranged to openin the ordinary way. Attached to the transom near its upper edge is theinwardly extending arm 3 provided with an angular extension at its innerend which is connected to one end of the elbow which will be more fullyherein- 46 after described. The arm 3 forms the controlling arm by meansof which the transom is moved.

Secured to the casing 1 is a plate 5. This plate 5 is formed with anoutwardly extending ear 6 to which'a link 7 is pivoted and this linkextends outwardly therefrom and is pro vided near its outer end with astop 8 while a suitable aperture 9 is provided near the inner end ofsaid link and is adapted to re ceive the hooked end ofa suitableconnecting element for the spring wl'nch'willbe more Iully herein'aiterdescribed. The extreme outerend of the link 7' is pivotally connected asat '10 to a link 11 the opposite end of which 1s ap'ertured topivotallyreceive theend of the arm 3. An extension '12'isiiormed on thelink 11 and projects beyond the end to which the link 7 is pivoted andthis extension'12 is apertured at-13fto3 receive the uppermost d link ofa suitable chain 14 or other suitable flexible member. 7 This extension12 is adapted to engage the stop-8'when the transom is in open positionand thus the links 7 and 11 are prevented from moving beyondapredetermined point. I

Extending through the opening 9 is a suitable hook 15 formed at thelower end of a connecting element 16, the upper end of which is providedwith an eye 17 to which the lower end of a tractile coil spring 18 isconnected. The upper end of said coil spring is connected to a screw eye19 which is attached tothe casing 1. g

It will be apparent from the ir'oregoing that in useassuming that thetransom is closed, pull is exerted on the chain 14 thus causing the linkll to. swing on the pivot 10 and tend topullthe upper end of said linkoutwardly thus moving the" transom on its hinge. The swinging movementof the} transom willswing the link 11 beyond the perpendicular andsimultaneously swing the link 7 downwardly until the links assume thepositions shown in Fig. '3 at which time the transom is fully open, Whenit is desired to close the transom, pull is again exerted on the chain14 thus breaking the elbow-joint formed by the links 7 and '11 and duetoy the pull of the spring 18 the transom will be moved to closedposition.

While in the foregoing there" has been shown and described the preferredembodiment of this invention, it is tobe understood that such changesmay be made in the combination and arrangement of-part-s as will fallwithin the spirit and scope of the invention as claimed.

What-is claimed is p In a closure operator, the combinationwith a hingedclosure and'a fixed support, a link pivoted to said closure, a secondlink, said second link being pivoted to said fixed support and at'apoint intermediate its ends to the first link to provide a free endextension on the first link beyond the last mentioned" pivot, a springconnected to the second link adjacent its pivotal connection with thefixed support and connected to the fixed support substantially abo vethelast mentioned pivotal connection, a flexible operating member connectedto the extension, and a stop on said second link to cooperate with saidextension when the closure is in fully openedposition said springoperating to hold the hinged closure in closed position, in oneadjustment of saidlinks and in another adjustment with t the extensionengaging the stop holding the links in extended relation with theclosure in openposition, pull on saidfiexible member in the samedirection and against the tension of said spring operating to releasethe closure from its position either when open or closed, the tension ofthe spring completing the movement whenpull on the flexible member isrelieved.

In testimony whereof I aflix my signature.
